The twin paradox uses the symmetry of time dilation to produce a situation that seems paradoxical. In the introductory film clip, we saw that time was dilated when observed from frames of reference with a constant relative velocity v. There is an animation and analysis below, but let's introduce it with a cartoon.<br />

There is an animation and analysis below, but let's introduce it with a cartoon.<br />
<br />
<b>The really strange thing about time dilation is that it is symmetrical</b>: if you and I have relative motion, then I see your clock to be running slow, and you see mine to be running slow. (Revise time dilation.) This is just one example of the weird logic of Einstein's theory of Special Relativity. The theory is counter-intuitive, because most of us are unfamiliar with measurements made at speeds approaching c, the speed of light. Because of this, it is fun to attempt to prove that it is wrong. Surely it's possible to make a paradox out of the symmetry of time dilation? Let's see.<br />
<br />
Jane and Joe are twins. Jane travels in a straight line at a relativistic speed v to some distant location. She then decelerates and returns. Her twin brother Joe stays at home on Earth. The situation is shown in the diagram, which is not to scale.<br />
<br />
Joe observes that Jane's on-board clocks (including her biological one), which run at Jane's proper time, run slowly on both outbound and return leg. He therefore concludes that she will be younger than he will be when she returns. On the outward leg, Jane observes Joe's clock to run slowly, and she observes that it ticks slowly on the return run. So will Jane conclude that Joe will have aged less? And if she does, who is correct? According to the proponents of the paradox, there is a symmetry between the two observers, so, just plugging in the equations of relativity, each will predict that the other is younger. This cannot be simultaneously true for both so, if the argument is correct, relativity is wrong.<br />

When one thinks of the "present moment," we usually connote it with something meaningful to him or her. Can we have a "meaningless" present moment? ....like waiting forever at the airport for your plane to arrive or depart????

Hyper-cool Marciel!!! I rather suspected something of the sort.<br />

The other thing that occurs to me is how 'time'seems to slow down dramatically when you are facing an accident (for example. Now why would that be?
